TECHNICAL FIELD

This application relates to a system or method for effectively operating a stealth mode of an emergency vehicle.

BACKGROUND

When emergency situations such as occurrences of crimes, disasters, car accidents, etc. take place, emergency vehicles will communicate with a control headquarter or another emergency vehicles to share information necessary for their own missions such as following or chasing suspects or cars driven by suspects, rescuing of victims, etc. However, the information being shared among related entities may include sensitive information on a certain emergency vehicle, so in case of the information is eavesdropped or hijacked by criminals, the whole mission can be in jeopardy.

Thus, there is a need for a system controlling emergency vehicles to be operated in a stealth mode, if necessary, where data is suspended from being transmitted.

DETAILED DESCRIPTION

The present disclosure may be understood more readily by reference to the following detailed description of the disclosure taken in connection with the accompanying drawing figures, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed disclosure.

Also, as used in the specification and including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value.

The phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

The term “emergency vehicle (EV)” includes, but are not limited: a police vehicle, an ambulance, a fire truck, etc.

The term “stealth mode” refers to a mode where an EV or a remote server at a control headquarter in communication with the EV suspends at least one data from being transmitted to another device (e.g., another remotely located from the EV or the remote server).

FIG. 1 depicts an example environment where an EV 10 communicates with another entities such as another EV 10 a, other vehicles 30 a to 30 d, and a control headquarter 25 according to an embodiment of the present disclosure.

When emergency situations such as occurrences of crimes, disasters, and car accidents, an EV 10 at interest, a peer EV 10 a, a control headquarter 25 and/or other vehicles 30 a to 30 d (e.g. vehicles which are not EVs) may exchange various data 80 over a road through a communication network 15 or a direct wireless channel, as depicted in FIG. 1.

The Data 80 being exchanged among the above-mentioned entities may include sensitive information that should not be shared with unauthorized individuals such as surveillances, criminals, police personnel not involved in the mission of the EV 10 or operators of the EV 10, etc.

For example, in order to ensure the EV 10's safety during traveling over the road, a geofence (e.g., 81 of FIG. 3A or 84 of FIG. 3B) can be generated by the control headquarter 25 or the EV 10. The geofence refers to a safety zone of the EV 10 which allows the EV to traverse the traffic safely. Example embodiments regarding generating and transmitting of the geofence of an emergency vehicle are disclosed in Applicant's copending U.S. patent application Ser. No. 16/243,692, filed on Jan. 9, 2019, entitled “SYSTEM AND METHOD FOR VELOCITY-BASED GEOFENCING FOR EMERGENCY VEHICLE”, the entire disclosure of which is incorporated by reference herein. As disclosed in U.S. patent application Ser. No. 16/243,692, filed on Jan. 9, 2019, a remote server 20 of the control headquarter 25 may generate a geofence based on an emergency indication signal (e.g., see 83 of FIG. 3A) which is transmitted from the EV 10. The emergency indication signal can include EV-related data 82 such as a location of the vehicle, a velocity of the vehicle, and an ID of the EV 10. Thus, in this case, the Data 80 being exchanged can be the EV-related data 81 transmitted from the EV 10 to the control headquarter 25 and/or the geofence 84 transmitted from the control headquarter 25 to other vehicles 30 a to 30 d.

In another scenario where the geofence is generated and transmitted by the EV 10, the EV 10 generates a geofence 81 based on the EV-related data 82. In this case, the Data 80 being exchanged can be the geofence 81 and/or the EV-related data 82 transmitted from the EV 10 to other vehicles.

In still another scenario where the EV 10 is a police car traveling to an emergency scene (e.g., crime scene), chasing or following suspects or cars driven by suspects (e.g., the EV 10 is an undercover police car), the Data 80 may include messages 83 exchanged among the EV 10, the EV 10 a and/or the control headquarter 25. More particularly, the messages 83 exchanged among the EV 10, the EV 10 a and/or the control headquarter 25 can include, but are not limited: an ID, a location, a velocity, a moving direction, etc. of a suspect or suspect vehicle which can help them to conduct their missions such as chasing or arresting the suspects or the suspect vehicle. Some of such Data 80 can be so sensitive, so in case of the information is eavesdropped or hijacked by criminals, the whole mission can be in jeopardy.

Thus, in some cases, upon receiving or detecting a control signal 350, the EV 10 is controlled to be in a stealth mode where at least a portion of the Data 80 is suspended from being transmitted, based on the control signal 350. The control signal 350 can be generated by an emergency subscriber device (see e.g., 100 FIG. 3A) of the EV 10 or the remote server 20 of the control headquarter 25.

In one embodiment, the stealth mode can be one selected from among one or more stealth modes. If the EV 10 is not in a stealth mode, the EV 10 is in a normal mode where none of the Data 80 is suspended from being transmitted. Hereinafter, the data subject to be suspended from being transmitted are referred to as “suspended data” for the sake of description.

In case of two or more stealth modes are set, the suspended data pertaining to the stealth modes can be different one from another, partially or exclusively.

For example, a certain security level is assigned to each of the suspended data based on how sensitive or important the data is. In addition, if the number of security levels is more than one, different security levels are assigned to each of the stealth modes. Information of the security levels assigned to each suspended data may be stored in memory (e.g., 202A of FIG. 2A).

FIGS. 2A to 2C depict example mapping relationships 202A to 202C among stealth modes, suspended data, and/or security levels according to an embodiment of the present disclosure.

Referring to FIGS. 2A to 2C, it is assumed that three stealth modes are set for the sake of simplicity. However, embodiments of the present disclosure are not limited thereto. For example, the number of stealth modes can be one, two, or more than three. Data 1 a to 3 a of FIG. 2A, Data 1 b to 3 b of FIG. 2B, and Data 1 c to 3 c of FIG. 2C are part of the Data 80.

By way of example only, referring particularly to FIG. 2A, the stealth mode 3 is associated with the security level 3 (e.g., highest security level), and when the stealth mode 3 is determined based on the control signal 350, Data 3 a is suspended from being transmitted. The stealth mode 2 is associated with the security level 2, and when the stealth mode 2 is determined based on the control signal 350, Data 2 a is suspended from being transmitted. The stealth mode 1 is associated with the security level 1, and when the stealth mode 1 is determined based on the control signal 350, Data 1 a is suspended from being transmitted. Here, Data 1 a to 3 a are assigned with the different security levels 1 to 3, respectively, and are exclusively different one from another. Further, in a normal mode, no security level is assigned and no suspended data is assigned thereto; for example, none of the Data 80 is suspended from being transmitted.

Referring now to FIG. 2B, no the security level is assigned to each stealth mode and suspended data. Data 1 b to 3 b are exclusively different one from another.

Referring now to FIG. 2C, the stealth mode 3 is associated with the security level 3 (e.g., highest security level), and when the stealth mode 3 is determined based on the control signal 350, all Data (e.g., Data 1 c to 3 c) are suspended from being transmitted; for example, none of the Data 80 can be transmitted. The stealth mode 2 is associated with the security level 2, and when the stealth mode 2 is determined based on the control signal 350, Data 1 c and 2 c are suspended from being transmitted. The stealth mode 1 is associated with the security level 1, and when the stealth mode 1 is determined based on the control signal 350, Data 1 c is suspended from being transmitted. Here, as Data 3 c has the highest security level, Data 3 c remains to be suspended from being transmitted at all kinds of stealth modes 1 to 3. Further, Data 2 c, which has a lower security level than Data 3 c, but higher security level than Data 1 c, is suspended from being transmitted at stealth modes 2 and 3 and can be transmitted in stealth mode 1. Data 1 c, which has the lowest security level, is suspended from being transmitted at stealth mode 3 and can be transmitted in stealth modes 1 and 2. In this embodiment with reference to FIG. 2C, the suspended data pertaining to the stealth modes can be partially different one from another while Data 2 c is commonly suspended from being transmitted in stealth modes 2 and 3 and Data 3 c is commonly suspended from being transmitted in all stealth modes 1 to 3.

FIG. 3A is a block diagram illustrating an example emergency subscriber device 100 according to an embodiment of the present disclosure. FIG. 3B is a block diagram illustrating an example remote server 20 according to an embodiment of the present disclosure.

In one embodiment, the emergency subscriber device 100 can be installed as a part of the EV 10, or a wearable or portable device attached to the EV 10. The emergency subscriber device 100 is configured to generate/process/transmit a portion of the Data 80.

Referring particularly to FIG. 3A, the emergency subscriber device 100 includes a controller 115, an input device 140, an output device 150, a communication device 130 and one or more sensor devices 160. The controller 115 may include at least one processor 110 and a memory 120 coupled to the processor 110.

In one embodiment, when the EV 10 is in an emergency state where it heads to an emergency scene, the emergency subscriber device 100 may collect the EV-related data 82 using the sensor devices 160, determine a geofence 81 based on the collected EV-related data 82 using the controller 115, and transmit the geofence 81 to other vehicles 30 a to 30 d using the communication device 130. In another embodiment, the emergency subscriber device 100 may trigger an emergency state and transmit an emergency indication signal 83 to the remote server 20 using the transmitter 132. The emergency indication signal 83 indicates that the EV 10 is in an emergency state, and upon receiving the emergency indication signal 83, the remote server 20 may generate and transmit a geofence 84 to other vehicles 30 a to 30 d for providing an alert of the EV 10. In this case, the emergency indication signal 83 may include an ID of the EV, and optionally, various EV-related data such as a type of the EV, a location of the EV, a velocity of the EV, or the like.

The communication device 130 may include a transmitter 132 and a receiver 134. For example, the sensor data such as the location and the velocity can be collected using sensor devices 160 including, but are not limited to: an accelerometer, a global positioning system (GPS) receiver, a velocity sensor, a motion sensor, infrared light sensors, radar, laser radar, cameras, a gyroscope, or the like. The collected EV-related data 82 may include an ID of the EV, a type of the EV, a location of the EV, a velocity of the EV, or the like and may be stored in the memory 120 or other storage (not shown). For example, the transmission or suspension of data may be controlled by controlling activation or deactivation of the transmitter 132 based on the control signal 350.

The input device 140 can be, but is not limited to: a keyboard, a touch screen, an audio input system, a voice recognition system, or the like. The output device 150 can be, but is not limited to: a display, a screen, a speaker, a light, a siren, a visual system, an audio system, or the like.

In addition, the memory 120 includes program instructions executable by the processor 110 to perform functions or operations of the emergency subscriber device 100 described in the present disclosure. The processor 110 reads the stored data which have been collected from the sensor devices 160 and processes to generate the geofence 81 that will be transmitted to other vehicles 30 a to 30 d through the transmitter 132 of the communication device 130. In one embodiment, the receiver 134 of the communication device 130 can be used to receive a control or confirmation signal from the remote server 20.

The communication network 15 may be implemented using on a wireless communication technique based on radio-frequency identification (RFID), code division multiple access (CDMA), global system for mobile communication (GSM), wideband CDMA, CDMA-2000, time division multiple access (TDMA), long term evolution (LTE), wireless LAN, Bluetooth, or the like. The communication device 130 may be implemented to support at least one of the above-mentioned communication techniques.

Referring further to FIG. 2B, the remote server 20 includes a controller 215 which may include a processor 210 and a memory 220 coupled to the processor 210, a communication device 230, and input device 240. The remote server 20 may reside on a network infrastructure or on a third-party service provider, such as a cloud storage and computing system.

The communication device 230 includes a transmitter 232 and a receiver 234. The communication device 230 may be implemented to support at least one of the above-mentioned communication techniques such as RFID, CDMA, GSM, wideband CDMA, CDMA-2000, TDMA, LTE, wireless LAN, Bluetooth, or the like. The input device 240 can be, but is not limited to: a keyboard, a touch screen, an audio input system, a voice recognition system, or the like.

The suspension of the Data 80 from being transmitted is controlled using the control signal 350 (e.g., 350 a of FIG. 3A and 350 b of FIG. 3B) which can be provided by the emergency subscriber device 100 or the remote server 20.

Example of Control Signal being Provided by Emergency Subscriber Device

In one embodiment, the control signal 350 a can be provided by the controller 115 of the emergency subscriber device 100 based on a user (e.g., operator of the EV 10) input through the input device 140. By way of example only, a selection menu for either a normal mode and at least one stealth mode may be implemented in the input device 140, as exemplary depicted in FIG. 4.

In the example selection menu shown in FIG. 4 where a normal mode 141 and three stealth modes 142 to 144 are provided, it will be apparent that the number of stealth modes implemented in the input device 140 can be one, two, or more than three. For example, the selection menu may include a specific button, or the like which allows the user to selectively suspend specific data (e.g., geofence, location, velocity, or ID of the EV 10).

In another embodiment, the control signal 350 a is provided by the controller 115 of the emergency subscriber device 100 based on program instructions stored in the memory 120. For example, the controller 115 receives one or more program input parameters through the input device 140 or the sensor device 160 and determines one of the normal mode and the at least one stealth mode in which the EV 10 shall be operated, based on the program instructions and/or the one or more program input parameters. In this case, the one or more program input parameters may include, but are not limited: a current location, a velocity, ID, etc. of the EV 10, a current time, or the like.

FIG. 5A depicts an example flow chart explaining as to how the operation mode of the EV 10 is controlled according to program instructions when the control signal is generated by the EV according to an embodiment of the present disclosure.

Referring to FIG. 5A, in step S510 a, the EV 10 may be operated in one (e.g., referred to as a “first mode”) of the normal mode and the at least one stealth mode.

In addition, the controller 115 of the emergency subscriber device 100 may receive one or more program input parameters from the sensor device 160, the remote server 20, or another storage mediums (S520 a) and determines if a trigger condition for the first mode to be switched to another mode (e.g., referred to as a “second mode”) of the normal mode and the at least one stealth mode (S530 a). It is noted that the terms “first mode” and “second mode” are only used in the specification of the present application for the sake of description, but are not necessarily applied to the claims in a same manner.

If the controller 115 determines based on the received program input parameters and/or the program instructions that the trigger condition is met (YES), the controller 115 may generate a control signal 350 a to switch the operation mode of the EV 10 (more particularly, e.g., emergency subscriber device 100) from the first mode to the second mode (S540 a). For example, if it is assumed in S510 a that the EV 10 is operated in the normal mode, the operation mode of the EV 10 will be switched to one of the at least one stealth mode. As a further example, if it is assumed in S510 a that the EV 10 is operated in one of the at least one stealth mode, the operation mode of the EV 10 will be switched to the normal mode or another of the at least one stealth mode.

If the controller 115 determines based on the received program input parameters and/or the program instructions that the trigger condition is not met (NO), the controller 115 might not generate the control signal 350 a to maintain the current operation mode (e.g., the first mode) of the EV 10 (more particularly, e.g., emergency subscriber device 100).

Example of Control Signal being Provided by Remote Server

In one embodiment, the control signal 350 b can be provided by the controller 215 of the remote server 20 based on a user (e.g., operator of the remote server 20 at the headquarter 25) input through the input device 240. A selection menu for either a normal mode and at least one stealth mode may be implemented in the input device 240. The selection menu of the input device 240 has a similar feature to the selection menu of the input device 140. Thus, duplicate description thereof will be omitted for the sake of simplicity.

In another embodiment, the control signal 350 b can be provided by the controller 215 of the remote server 20 based on program instructions stored in the memory 220. For example, the controller 215 may receive one or more program input parameters from the emergency subscriber device 100 and determine one of the normal mode and the at least one stealth mode in which the EV 10 is operated based on the program instructions and/or the one or more program input parameters. In this case, the one or more program input parameters may include a current location, a velocity, ID, etc. of the EV 10 and a current time.

FIG. 5B depicts an example flow chart explaining as to how the operation mode of an EV is controlled according to program instructions when the control signal is generated by the remote server 20 according to an embodiment of the present disclosure.

Referring to FIG. 5B, in step S510 b the EV 10 may be operated in one (e.g., referred to as a “first mode”) of the normal mode and the at least one stealth mode.

In addition, the controller 215 of the remote server 20 may receive one or more program input parameters from the emergency subscriber device 100 (S520 b) and may determine if a trigger condition for the first mode to be switched to another mode (e.g., referred to as a “second mode”) of the normal mode and the at least one stealth mode (S530 b).

If the controller 215 determines based on the received program input parameters and/or the program instructions that the trigger condition is met (YES), the controller 215 may generate a control signal 350 b and transmit the control signal 350 b to the emergency subscriber device 100 in order to switch the operation mode of the EV 10 (more particularly, e.g., emergency subscriber device 100) from the first mode to the second mode (S540 b). For example, if it is assumed in S510 b that the EV 10 is operated in the normal mode, the operation mode of the EV 10 will be switched to one of the at least one stealth mode. As a further example, if it is assumed in S510 b that the EV 10 is operated in one of the at least one stealth mode, the operation mode of the EV 10 will be switched to the normal mode or another of the at least one stealth mode.

If the controller 215 determines based on the received program input parameters and/or the program instructions that the trigger condition is not met (NO), the controller 215 might not generate the control signal 350 b, so that the current operation mode (e.g., the first mode) of the EV 10 can be maintained.

The program module may be programmed into the integrated circuits of the processor (e.g., 4010). In an exemplary embodiment, the program module may be stored in the memory system (e.g., 4030) or in a remote computer system storage media.

The computing system 4000 may include a variety of computing system readable media. Such media may be any available media that is accessible by the computer system (e.g., 4000), and it may include both volatile and non-volatile media, removable and non-removable media.
